filtration. The outflow from the activated carbon layer will bring some tiny carbon particles and fallen microorganisms, which will be removed by a sand filter in the end. To improve the filtration efficiency, chlorination and enhanced coagulation were done firstly before this procedure. Advanced oxidation processes (AOPs) are attractive alternatives for traditional water treatments and are receiving considerable attention. The proposition to optimize coagulation with AOPs is promising for organic pollutants degradation because, as a preoxidant, they can break down organic and inorganic contaminants to total decomposition.
